Having just joined this list, and entered in the middle of this
discussion, perhaps I'm missing the point? OO generally refers to the
interaction of pieces of code running in a single process on a single
computer, whereas SOA refers to the interaction between different
processes running on (possibly) different computers.
Of course, there are plenty of grey areas - "distributed object"
systems like CORBA or RMI, etc. As much as anything, I think SOA is a
state of mind - trying to expose as much of your code as possible to
remote code written by other people running on other computers.
